Half ion equation
WebCombining the half-reactions to make the ionic equation for the reaction. The two half-equations are: H 2 O 2 + 2e- 2OH-Cr(OH) 6 3- + 2OH- CrO 4 2- + 4H 2 O + 3e-If you multiply one equation by 3 and the other by 2, that transfers a total of 6 electrons. Finally, tidy up the hydroxide ions that occur on both sides to leave the overall ionic ... http://www.molecularsoft.com/help/Half_Reaction.htm
